This document provides design details for an oil tanker ship with the following key specifications:
- Ship Type: Oil Tanker with capacity of 2900 tonnes
- Route: Between Chittagong and Dhaka in Bangladesh
- Speed: 10 knots
It includes principal particulars, general arrangement drawings, lines plans, hydrostatic calculations and curves, resistance and power calculations, engine and gearbox selection, and designs for the rudder, steering arrangement, and other systems. The document compares the updated design specifications to previous specifications.
The document discusses navigating ships through muddy waters and defining the "nautical bottom". It explores using rheological properties of mud as a criterion for the nautical bottom, as mud is a non-Newtonian fluid whose properties impact ship controllability. Useful configurations for further research include studying forces on structures in mud layers and ship manoeuvring above mud with varying properties to better link mud characteristics to ship behavior and operational limits. A multidisciplinary approach is needed combining rheology, CFD, and ship modelling.
The document summarizes a student project to design a water taxi for 100 passengers on the Sadarghat-Ashulia route in Bangladesh. Key details of the proposed design include a length of 24.9 meters, capacity for 106 people, and selection of a Yanmar 4JH4-HTE engine with 186 horsepower. The students updated their general arrangement, lines plan, hydrostatic calculations, and stability analysis based on a reduced displacement of 74.88 tons from the previous 123.48 tons.
This document summarizes the key responsibilities of a naval architect. It discusses how naval architects design ship structures, assess stability, analyze resistance and powering needs, evaluate seakeeping performance, and follow a design process. For each area, it provides a brief example and overview of the technical considerations and calculations involved. The overall message is that while kids may dream of designing grand ships, as a naval architect the work involves both large and small projects, using engineering skills to ensure vessels can float and operate safely.
1. The document discusses the various components of ship resistance including viscous resistance, wave-making resistance, and air resistance.
2. Viscous resistance is affected by factors like Reynolds number and hull shape, with slender hulls reducing the normal component.
3. Wave-making resistance drastically increases above the hull speed as transverse wave length approaches ship length. Bulbous bows can reduce bow wave resistance.
4. Total resistance is calculated from coefficients of viscous, wave-making, and air resistance, with model tests needed to determine wave-making coefficient.
Structural Design of 38 m Special Purpose Vessel in Aluminium AlloyMurat TOSUN
The general objective of the thesis is to carry out the structural design process of a high speed special purpose vessel which is a supply unit for offshore platforms, suitable for transporting technical personnel, cargo on deck and liquid cargo: fresh water and gasoil with a flash point above 60°C.
The design is developed in Rodriquez Cantieri Navali Spa. which has good experience with aluminium alloy vessels. Although the thesis aims to investigate the structural design of the vessel, it is needed to follow from preliminary design stages by providing its main particulars, hull form, capacity plan, stability analysis as well as the general arrangement.

Numbers have various cultural superstitions around the world. In Thai culture, odd numbers are considered lucky while 9 symbolizes progress and wealth. In Chinese culture, 8 symbolizes prosperity while 4 is considered unlucky. These beliefs originated long ago and were passed down through generations, gaining popularity. However, superstitions can also result in wasted effort and money when taken too far, such as with lotteries. Rural areas of Thailand practice superstitions related to rain and agriculture, such as using cats to cry out and summon rain. These beliefs reflect the importance of agriculture and adaptation to the local climate and community.

This chapter discusses perfect competition in markets. It begins by introducing lithium as an important input for batteries that has seen rising demand but falling prices. This is explained by the entry of new firms into the lithium industry. The chapter then outlines learning objectives and a chapter outline covering characteristics of perfect competition, how individual firms determine output levels, short-run profits, supply curves, and long-run equilibrium with entry and exit of firms. It also discusses how price is determined through the interaction of market supply and demand.
The report follows a top-down approach, starting with a brief on developed and emerging economies, then moving on to Egypt, covering Egypt’s political & macro-economic picture, stock market assessment, comparable analysis with other emerging markets, sectorial analysis, and ultimately our favorite picks from stocks trading on the Egyptian stock market.
This document discusses different views on beauty, appearance, and attraction. It presents several statements about beauty being subjective and dependent on character rather than physical appearance alone. It also asks for the reader's opinions on whether they believe in love at first sight or have any interest in tattoos or piercings.

The document provides an overview of basic economic concepts. It discusses:
- Economics is the study of how individuals and societies deal with scarcity. Scarcity means that resources are limited and our wants are unlimited, so we must make choices about how to use resources.
- Microeconomics studies small economic units like individuals and firms, while macroeconomics looks at the overall economy. Positive economics makes factual statements, while normative economics includes value judgments.
- The production possibilities curve (PPC) model shows the tradeoffs between producing different goods given limited resources. Points on the PPC are productively efficient, while the optimal point depends on societal wants.
- Comparative advantage explains why countries
Mass digitization projects across the country are working together to digitize large amounts of media and make it available online in order to more broadly share information. The document provides resources for teachers on copyright and fair use when using protected works, including checking if a work is already licensed for campus use, freely available on the open web with an implied license, or requiring permission.

As the arena of digital marketing options continues to increase and change, the challenge of deciding what to do and how to do it equally expands. In efforts to discuss how various tactics interact with one another to accomplish the goals of the business game plan, we have devised the “digital marketing triangle offense.”
When helping a client run the digital marketing triangle offense, we look at three areas with natural boundaries:
The top of the triangle is the organization’s website. In keeping with the basketball analogy, the website is the home court advantage. Think of a sports arena: The facility bears the markings of the home team’s intended brand. Intentional control and thoughtful planning occurs here.
The second section takes marketing efforts on the offensive, helping to tell the client’s story — stories, actually. This is for “content marketing,” which encompasses three main tactics: blogging, email and social media. As we introduce content marketing into the communications mix, we begin to discuss how the three sections relate to one another.
The third section — optimization — takes on a larger context than just the work of improving organic search. We look at landing page execution and calls to action, plus the possibility of a microsite. Search engine optimization, search engine marketing, advertising on social networks, banner ads and keyword strategies are all addressed in this area. We call optimization the strength-training portion of your plan. As with real-world conditioning, optimization is a practice that the public does not see until the results are worked out across the variety of marketing tactics.

For external implementation, it discusses informing parents about changes through letters and later sharing student success data with stakeholders.
Glyconutrients are 8 essential sugars that help with cell-cell communication and immune function. FoodState products use glycoproteins to effectively deliver nutrients to cells. Multivitamins can help supplement deficiencies, and research shows vitamins D and K can reduce cancer risks when levels are optimized through diet and supplements. Homeopathic medicines from Boiron are reliable, respected, and researched to safely treat aches, pains, and infections.
1) Truth is something that is simply true regardless of what people believe, such as mathematical or logical facts.
2) Knowledge is information gained from experience that is justified by evidence and believed by people, though it exists in varying degrees.
3) Knowledge requires a high degree of certainty since it must be justified and true, while truth itself does not require certainty as something can be true whether believed or not.
This document describes an experiment to investigate the relationship between the volume of water in a rectangular tank and the period of seiche waves. The experiment involved recording video of standing waves formed in a tank when shaken, for different water volumes. Position-time graphs were plotted from the videos and fitted with sine curves, and the period was calculated from the curve parameters. The results showed an inverse relationship between the period squared and volume, as predicted by theory. The experiment aimed to understand how seiche waves are affected by water depth and volume.
This chapter discusses the history and patterns of energy consumption. It describes how early humans exploited wood and coal as energy sources to enable settlements and industry during the Industrial Revolution. The automobile further increased oil demand and drove suburban development patterns. Government policies influence transportation and electricity infrastructure, affecting national energy usage trends. Energy economics and politics, like OPEC setting oil prices, also impact consumption trends worldwide.

3. L’idea progettuale
p g
OpenSHIP prevede l’impiego di soluzioni che utilizzano in modo
sinergico calcolatori ad alte prestazioni (HPC - High
Performance Computing) e simulazioni di alta fedeltà del moto
del fluido attorno alla carena e all’elica basate su software
OpenSource.
Il software OpenSource, in alternativa o integrato con software
commerciale, permette di:
• ridurre il costo delle licenze;
• ottenere maggiori livelli di flessibilità e personalizzazione.
L’idea progettuale consiste nello sviluppo di un prototipo virtuale che tenga conto delle
reciproche influenze tra la scia generata dalla carena e il funzionamento dell’elica.
Si tratta di un obiettivo ambizioso perché tale procedura entrerebbe per la prima volta a far
parte degli standard di progettazione navale.
